NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 734,577, dated July 28, 1903.

tion shown in Fig. l if a train were moving y .To all wir/ont it may concern,.-

Beit known that I, GEORGE HENRY LAYNG, railway agent, a subject of the King of Great Britain, residing in .the town of ASault Ste. Marie, in the district of Algoma, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Nut- Locks, of which thel following is a specification. I

My invention relates to improvements in nut-locks; and the object of my invention is to more particularly design a nut-lock that can be easily and rapidly attached to a suitable base; and it consists, essentially, of a locking-bar provided with two U shaped rivet-slots in each of which operates a stout pin which may be secured to one of the fishplates or else to a separate base-plate.

turning, as hereinafter more particularly eX- plained.

Figure l is a side elevation of my nut-lock attached to a sh-plate joining the adjacent ends of two rails. Fig. 2 is an end elevation of my nut-lock and rails to which same is attached, showing the nut-lock in normal position. Fig. 3 is an end elevation of my nutlock and rails to which same is attached, showing said nut-lock out of engagement with the nuts it is designed to lock. Fig. 4 is a vertical section through the rail and sh-plate for same, showing the locking-bar secured to said sh-plate. Fig. 5 is a side elevation of a portion of an alternative form of the locking-bar.

In the drawings like letters of reference indicate corresponding parts in each figure.

A represents the two rails, which are secured together by the boltsB and iish-plates C.

In manufacturing my nut-lock I preferably provide same with a base-plate D of its own, which is of course manufactured so as to be placed adjacent one of the fish-plates and held thereagainst by means of the nuts E on the bolts B.

F is the locking-bar, provided with two U- shaped slots G, in which operates a stout pin H, secured to the base-plate D. In case the locking-bar F should be in the dotted posi- The said locking-bar is provided on its under side in-the right-hand direction the front wheels of same would strike against said locking-bar and move same down in the direction indicated by arrow with tail to position shownin full lines. As the under side of the saidlock ing-bar is provided with a suitable number of recesses I, which aredesigned tol closely.-` fitthe nuts E, it will be seen that when said Vlocking-bar is in normal position said nuts are prevented from turning. From Figs. 2, 3, and 4 it will be noticed that I preferably taper the locking-bar F, as shown, although I do not conne myself to so constructing same. As the Wheel .I moves toward the spectator same strikes the locking-bar F, and as same is wedge-shaped same is forced down into position shown in Figs. l, 2, and 4 and wedged tightly between the said stout pins and the base-plate. It will be noticed that the stout pins H are provided with broad heads O, which prevent said pins from moving out of thesaid U shaped slots. I of course do not confine myself to the construction shown of said stout pins nor to the manner shown for securing same to their supports.

P is any suitable lip by means of which the locking-bar can be raised upv or down by hand. It will be noticed that the said locking-bar is provided with a suitable number of recesses I, so that no matter in what direction the said locking-bar may be operated it will engage with the nuts E and lock same.

If desired, I may attach my locking-barF Vdirectly to one of the fish-plates, as shown inv wedge-shaped, as this constructionl` prevents rattling and has also a tendency to retain the locking-bar in its normal position.

It will be noticed from Fig. l that the U- shaped slots are constructed in the lockingbar in the same position in which the ordinary letler U is ordinarily printed on a page.

The lower corners a of the recesses I are IOO rounded, as shown, so that when the lockingbar F is moved so as to lock the nuts the sides of same may be moved as closely as possible to the engaged sides of nuts and prevent any loosening of same.

What I claim as my invention, and desire to secure by Letters Patent, is-

l. A nut-lock comprising a locking-bar provided with a suitable number of recesses in its under side, the sides of which recesses are designed to engage with the sides of nuts to be locked and lock same, the said locking-bar being further provided with two U-shaped slots, and a stout pin operating in each of said U-shaped slots, the said stout pins being designed to be secured to a base through which the bolts of the nuts pass, and against which the nuts are jammed.

2. A nut-lock comprising a locking-bar, tapered from its upper end to its lower end, provided with a suitable number of recesses in its under side, the sides of which recesses are designed to engage with the sides of nuts to be locked and lock same, the said locking-bar being further provided with two U-shaped slots, and a stout pin operating in each of said U-shaped slots, the said stout pins being designed to be secured to a base through which the bolts of the nuts pass, and against which the nuts are jammed.

3. A nut-lock comprising a locking-bar, tapered from its upper end to its lower end, provided with a suitable number of recesses in its under side, the sides of which recesses are designed'to engage with the sides of nuts to be locked and lock same, the said locking-bar being further provided with two U-shaped slots; a stout pin operating in each'of said U-shaped slots, the said stout pins being designed to be secured to a base through which the bolts of the nuts pass, and against which the nuts are jammed, and a lip attached to said looking-bar to enable same to be moved.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

GEORGE HENRY LAYNG.
